Re: [hiaps] Hybrid access bar bof

["Henderickx, Wim (Wim)" <[e-mail]>]

I believe there is several solutions today in the market and some require more adaptations than others.
E.g. If you give the same IP address and multiple links/Interfaces (ETH, xG, WIFI) and the IP stack accepts that, it can do packet or flow based hashing. Tested and working with openWRT, Android, IOS, Linux. Some stack prefer one interface over another and others have more extensive hashing/loadbalanicng mechanisms, but this is implementation specific.
The nice thing is that you don’t consume extra ip addresses and most stacks support this today. Works on smartphones, residential GW and enterprise GW(s).
